FIELD
The present disclosure relates, in general, to a flash suppressor
for a firearm, and more particularly, to a flash suppressor that
includes a plurality of tines formed in a way to better reduce
muzzle flash and eliminate any unwanted ringing caused by resonance
of the tines.
BACKGROUND
In order to fire a projectile, a firearm utilizes an ignited
propellant to create a high-pressure pulse of hot gases behind the
projectile to force the projectile down the barrel of the firearm.
When a projectile is fired from most firearms, a visible signature
or flash, commonly referred to as "muzzle flash," exits the barrel
of the firearm after the discharge of the projectile. Muzzle flash
has a number of undesirable effects, including temporarily
impairing the vision of the person using the firearm, particularly
in cases where the person is using the firearm in limited light
conditions. Muzzle flash is caused by a number of factors,
including propellant gases exiting the barrel of the firearm after
the projectile and the mixture of such gases with the ambient air.
The severity of muzzle flash depends on number of factors,
including the type of firearm and ammunition being used. Muzzle
flash is often more severe in firearms with shorter barrels because
there is less distance for the propellant to be consumed before
exiting the barrel.
Muzzle flash can be reduced through the use of a flash hider, which
attaches to end of the firearm barrel and mechanically disperses
the gases exiting the firearm in a way to reduce the visible flash.
Flash hiders come is variety of designs, including the use of a
plurality of prongs, or tines, extending from the end of the barrel
of firearm. However, when flash hiders use tines to reduce muzzle
flash, the high-pressure gases exiting the firearm can cause the
tines to resonate and cause an undesirable ringing sound. In
addition, tines used in certain flash hiders may be relatively long
and vary in length. Tines that vary in length can create a number
of difficulties, including, for example, making it difficult to
attach other firearm components such as a noise suppressor to the
flash suppressor. Having tines of different length also can result
in the longer tine catching on debris and other impediments during
field use and absorbing the majority of the impact if the firearm
receives an impact at its distal end, such as being dropped on its
barrel.
Accordingly, there is a need for a flash suppressor that
effectively suppresses muzzle flash without creating any ringing or
other undesirable sound effects, but which can also be effectively
used in a field environment and designed so that other firearm
components can be easily attached to it.
BRIEF SUMMARY
Certain embodiments include flash suppressors for firearms that
effectively suppress muzzle flash using a plurality of tines of
equal mass oriented in a helical manner. In certain embodiments,
each tine extends to the same plane perpendicular to the distal end
of the flash suppressor and the cuts used to form the tines vary in
length and/or width in order to prevent an audible ringing or other
undesirable effects. In addition, in certain embodiments, each tine
contains a groove in its outer surface where each groove can be
varied in length, width and/or depth in order to reduce the weight
of the tine and to achieve other desired effects. In aspects of
certain embodiments, a circular face of the flash hider located
adjacent to the muzzle contains a bore that has the same
circumference as the bore formed by the internal surfaces of the
tines.
The embodiments of the invention described herein are defined by
the claims. Further advantages and a more complete understanding of
the embodiments will be apparent to persons skilled in the art from
review following detailed description of various embodiments and
appended claims.

DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS
While various aspects and features of certain embodiments have been
summarized above, the following detailed description illustrates a
few exemplary embodiments in further detail to enable one of skill
in the art to practice such embodiments. The described examples are
provided for illustrative purposes and are not intended to limit
the scope of the invention.
In the following description, for the purposes of explanation,
numerous specific details are set forth in order to provide a
thorough understanding of the described embodiments. It will be
apparent to one skilled in the art, however, that other embodiments
of the present inventions may be practiced without some of these
specific details. Several embodiments are described herein, and
while various features are ascribed to different embodiments, it
should be appreciated that the features described with respect to
one embodiment may be incorporated with other embodiments as well.
By the same token, however, no single feature or features of any
described embodiment should be considered essential to every
embodiment of the invention, as other embodiments of the invention
may omit such features.
Unless otherwise indicated, all numbers used herein to express
quantities, dimensions, and so forth should be understood as being
modified in all instances by the term "about." In this application,
the use of the singular includes the plural unless specifically
stated otherwise, and use of the terms "and" and "or" means
"and/or" unless otherwise indicated. Moreover, the use of the term
"including," as well as other forms, such as "includes" and
"included," should be considered non-exclusive. Also, terms such as
"element" or "component" encompass both elements and components
comprising one unit and elements and components that comprise more
than one unit, unless specifically stated otherwise.
FIG. 1 is a side view of an exemplary flash suppressor 10 in
accordance with an embodiment of the present invention. FIG. 2 is a
perspective end view from the proximal end of flash suppressor 10
in accordance with an embodiment of the present invention. As
shown, flash suppressor 10 includes a central axis 12, a proximal
end 14, and a distal end 16. As used in this detailed description,
the term "proximal" is used to refer to the end of the component or
element closest to the barrel of the firearm and the term "distal"
is used to refer to the end of the component or element farthest
from the barrel of the firearm. Proximal end 14 of flash suppressor
10 includes a threaded interface 18, which is used to connect flash
suppressor 10 to the muzzle of a firearm that is not shown in FIGS.
1 and 2. Flash suppressor 10 includes an angular shoulder 20 and
threaded interface 22, which can be used to help connect flash
suppressor 10 to another firearm attachment such as a noise
suppressor. Flash suppressor 10 also includes three tines 24, 26,
and 28. When a projectile is fired from a firearm attached to flash
suppressor 10, the gases proceed through the barrel of the firearm
into flash suppressor 10 and are dispersed by tines 24, 26, and 28
as explained in more detail below.
FIG. 3 is a perspective view of individual tine 24 of the flash
suppressor of FIG. 1. FIG. 4 is an exploded perspective view of the
flash suppressor of FIG. 1. As shown in FIG. 3, tine 24 is formed
in a helical shape. In this embodiment, tine 24 is formed using a
helical cut that can be measured in such a way whereby if tine 24
were extended 8.8 inches it would form a complete rotation around a
tube with a 0.9 inch diameter. In this particular embodiment, the
helical cut of each tine is oriented in clockwise, or right-handed
twist, when viewed from the direction of the projectile path
through flash suppressor 10. This is the same orientation of the
rifling in most firearms.
FIG. 4 further shows the embodiment of the flash suppressor of FIG.
1. Flash suppressor 10 has a base 30, which consists of the portion
of flash suppressor 10 from the distal end 14 through the proximal
end of angular shoulder 20. Base 30 has a circular face 32 that
contains bore 34. When a firearm is attached to flash suppressor
10, the muzzle of the firearm (not shown) attaches to threaded
interface 18 as shown in FIG. 2. The bore of the barrel of the
firearm aligns with bore 34. In this embodiment, the diameter of
bore 34 is the approximate size of the diameter of the bore in the
barrel of the firearm. As also shown in FIG. 4, tine 24 contains
groove 36, tine 26 contains groove 38, and tine 28 contains groove
39 wherein each groove is formed by making a cut of a certain width
and depth from the distal end of the suppressor. Each groove
reduces the weight of each tine, which improves the overall
performance of flash suppressor 10.
As the gases created from the firing of a projectile exit the
barrel, these expelled gases proceed through bore 34 and are
dispersed by tines 24, 26, and 28 shown in FIG. 4. Each tine has an
inner surface that receives the expelled gases through bore 34 and
disperses the gases into the ambient air to dramatically reduce, if
not completely eliminate, muzzle flash by rapidly cooling and
diluting the propellant gases as they exit the firearm barrel. More
specifically, tine 24 contains inner surface 40 and directs
expelled gases in the direction shown by arrow 42, which allows a
portion of the expelled gases to be dispersed and mixed with
ambient air through the cut between tine 24 and tine 28. Similarly,
tine 26 contains inner surface 44 and directs expelled gases in the
direction shown by arrow 46, which allows a portion of the expelled
gases to be dispersed and mixed with ambient air through the cut
between tine 24 and tine 26. Finally, tine 28 also contains an
inner surface, which is not directly shown but indicated by arrow
48. Inner face 48 of tine 28 directs expelled gases in the
direction shown by arrow 50, which allows a portion of the expelled
gases to be dispersed and mixed with ambient air through the cut
between tine 26 and tine 28.
FIG. 5 depicts the distal end view of flash suppressor 10 and, in
this particular embodiment, inner surfaces 40, 44, and 48 of tines
24, 26, and 28, respectively, form a bore that has substantially
the same diameter as bore 34. This particular spacing of tines 24,
26, and 28 helps to ensure that the expelled gases are dispersed
radially from the suppressor through the cuts between the tines.
This increases the rate in which the expelled gases are mixed with
the ambient air and reduces the chances of the gases igniting
unused propellant before they are expelled from flash suppressor
10.
In addition to significantly reducing, if not completely
eliminating muzzle flash, flash suppressor 10 also eliminates any
ringing caused by the resonance of the tines. As shown in FIG. 6,
in particular embodiments, cut 52 between tines 24 and 28 has a
length 54 that is longer than cut 56 between tines 24 and 26 that
has a length 58. Cut 60, which is shown in FIG. 7, has a length 62
between tines 26 and 28 and is located on the back side of flash
suppressor 10 in FIG. 6. In addition, the width of the cuts between
tines 24, 26, and 28 can also be varied. As shown in FIG. 6, width
64 is between tines 24 and 28 and width 66 is between tines 24 and
26. Width 68 between tines 26 and 28 is shown in FIG. 7 and is
located on the back side of flash suppressor 10 in FIG. 6. By
varying the length and width of the individual cuts, the potential
frequency of the individual tines can be varied to eliminate any
audible ringing. In a particular embodiment of flash suppressor 10,
which is designed to be used with a 0.223 caliber firearm, the
length and width of cuts 52, 56, and 60 that form tines 24, 26, and
28 are as follows:
TABLE-US-00001 Length 54 1.10 inches Width 64 0.3100 inches Length
58 1.05 inches Width 66 0.3214 inches Length 62 1.00 inches Width
68 0.3275 inches
With these particular dimensions, tines 24, 26, and 28 did not
create any audible ringing when used with a firearm. While not
shown in this particular embodiment, the frequency of tines 24, 26,
and 28 can alternatively be varied to prevent an audible ringing by
altering the dimensions of each groove 36, 38, and 39 in tines 24,
26, and 28, respectively, as shown in FIG. 4. In this particular
embodiment, the cuts 52, 56, and 60 that form tines 24, 26, and 28
each rotate at least 30 degrees around the central axis 12 (as
shown in FIGS. 1 and 2) from the start of each cut to the finish of
each cut.
In addition, as shown in FIGS. 6 and 7, in certain embodiments,
tines 24, 26, and 28 all extend to plane 70, which is perpendicular
to the distal end of the flash suppressor. When viewed from the
distal end, surfaces 78, 80 and 82 shown in FIG. 5 all contact
plane 70. In addition, as shown is FIG. 6, outer surfaces 72, 74,
and 76 of the tines 24, 26, and 28, respectively, are non-tapered.
In other words, the outer surface of each tine remains an equal
distance from the center of flash suppressor 10 such that the outer
diameter of the suppressor is same throughout the length of tines
24, 26, and 28. Extending tines 24, 26, and 28 to the same plane,
and keeping the outer diameter of the suppressor the same
throughout the length of the tines, helps ensure that flash
suppressor 10 is significantly easier to attach to other firearm
components such as a noise suppressor. In addition, tines 24, 26,
and 28 are much less susceptible to being entangled in debris and
other impediments during field use and uniformly absorb the impact
if, for example, the firearm, to which flash suppressor 10 is
connected, is dropped on its barrel. By varying the length and
widths of the cuts 52, 56, and 60, the mass of each of the tines is
the same, which ensures that the flash suppressor is balanced for
better performance.
While various embodiments of apparatus are described with--or
without--certain features for ease of description and to illustrate
exemplary aspects of those embodiments, the various components
and/or features described herein with respect to a particular
embodiment can be substituted, added, and/or subtracted from among
other described embodiments, unless the context dictates otherwise.
Consequently, although several exemplary embodiments are described
above, it will be appreciated that the invention is intended to
cover all modifications and equivalents within the scope of the
following claims.
